UPDATE: 2/20/16, Have this installed om my DROID MAXX, and Samsung Tablet. Still the best bar none! An excellent combination of functionality, ease of use, optional settings, and aesthetics all in one package. Obviously the development team thought this through. My continual search for a calculator officially ends with the King Calculator.

Weird lingering bug that never gets fixed: a zero (0) is never prepended to a number entry beginning with a decimal and it is an annoying quirk that forces us to always enter that 0 for real numbers -1 < x < 1 edit: glad you've been responsive with an eventual fix but the tone of previous reply was not appreciated. The frontline users are best at judging bug severity. I'll visit this calculator again and see if it competes at the level of my current solution.
